Filed: 1925-10-12
Abstract: 242,255. Bergmann Elektricitõts Werke Akt.-Ges. Oct. 30, 1924, [Convention date]. Picking - motions. -In looms wherein the shuttles are actuated by cam or crank operated pickers, the picking devices are operated independently of the speed of the rest of the loom so that a predetermined minimum force is exerted in all cases. The picking- cam 7 may be operated from a shaft 2, which is driven independently of the loom main shaft 1, though, as shown, the latter may be driven therefrom by bevel gearing and friction gearing 5, 6 giving a greater or less speed to the shaft 1. The cam 7 and a controlling-disc 8 may be loosely mounted on the shaft 2 and be connected thereto at the required times for picking by means of a coupling sleeve 12 and a pin 11 on a rod or arm 14 pivoted at 9 and controlled by a cam 13 on the shaft 1. The disc 8 causes the disengagement of the pin 11 after rotation of the cam 7 and disc 8, a braking-bar 10 stopping the cam 7 in the required position. Two picking-cams may be mounted on the shaft 1. In a modification, wherein the main shaft is tubular and concentric with the picking shaft, the pivot 9 is carried by the main shaft.

Title: Machine for packing and wrapping articles
Inventor: CLEGG FREDERICK WILLIAM
IPC: B65B11/32
Filed: 1957-08-12
Abstract: 906,379. Endless conveyers; rotary elevators. NOVOTECHNICS Ltd. Nov. 12, 1958 [Aug. 12, 1957], No. 25440/57. Class 78 (1). [Also in Group XVII] A machine for packaging a predetermined number of articles, such as apples, in a wrapper, comprises a plurality of troughs 5 on an intermittently moving endless conveyer 3, each trough carrying the predetermined number of apples to a transfer position below a step-by-step rotary wrapping head H. Each trough 5 is mounted on a link 3 of a pair of endless chains and the troughs 5 have flanges 7 that overlap the flanges of adjacent troughs. A plunger 8, acting through an opening in the base of a trough, transfers the contents of the trough, together with the wrapper, supplied from a roll R, into one of a series of grippers 10, 11 on the wrapping head. The plunger 8 has a dished or concave surface to maintain the apples in alignment during the transfer stroke. As the apples and wrapper move into the gripper at position I the wrapper is pressed downwardly against the sides of the apples. As the grippers 10, 11 close and move to position II, cam tracks cause folding blades 12 to close and overlap one another and collapse the edges of the wrapper around the pack in a superimposed manner. An electrically-heated member 25 then heat-seals the overlapping edges. At position IV a pair of rotatable claws grip the projecting ends of the wrapper and twist them to close the package. At position V the final package is released to fall on to a delivery tray. Centralizing apples to be packed.-On arrival of the trough 5 at the transfer position, end stops 30 (Fig. 2, not shown) move towards each other along the axis of the trough to centralize the apples therein and cause them to abut against each other. The end stops 30 rise with the plunger 8 but withdraw as the apples and wrapper enter the grippers 10, 11.

Title: Improvements in or relating to methods for treating corrosive gases to render them innocuous
IPC: C01B9/08
Filed: 1945-10-01
Abstract: Fluorine is removed from gases such as derive from the fluorination of hydrocarbons or the production of cobaltic fluoride by passing them over a mixture of a non-volatile metal fluoride, e.g. of the alkali or alkaline earth metals, and a metallic oxide or non-volatile metal chloride, e.g. the oxide or chloride of sodium, potassium, calcium, barium, magnesium, cadmium or zinc, the oxide or chloride forming only a single and non-volatile fluoride.  Preferably, the mixture or a component thereof is fusible below 1000 DEG  C., and the mixture is heated till fusion or partial fusion occurs, solidified and granulated. Generally, the mixture contains 25-50 per cent fluoride.  When it contains a chloride, the chlorine evolved may be removed from the effluent gas by passing it over hydrated lime or by washing with aqueous alkali.  The gases may be passed through towers containing increasing amounts of the oxide or chloride constituent, the last tower containing oxide or chloride free from fluoride.
Patent GB-784732-A (GB)
Title: Improvements relating to continuous production of corrugated reinforced plastic material
IPC: B29C53/24
Filed: 1955-09-06
Abstract: The invention of the parent Specification, which is essentially a process wherein glass fibre mat material is compressed by rollers between bands coated on their inner faces with resin and then corrugated in a heated chamber where the resin is also polymerized, the bands then being separated from the product, is modified by the omission of heating means at the corrugating stage.  The cold curing of the resin in the corrugating apparatus results from initially spraying a catalyzed resin onto one of the bands, e.g., a polyester resin with benzoyl peroxide added, and by spraying an accelerated resin, e.g. with dimethyl-aniline added, onto the other band.  The bands, and the fibre mat between them, are then passed vertically through the rollers, where the mat is impregnated and the resins are mixed.  The curing of the resin in the corrugated laminate is completed by allowing it to stand for about two days at room temperature or by passing it down a flat metal shoot, to remove part of the heat of reaction, and then through a chamber heated at 80 DEG -90 DEG C.  Examples are given of suitable catalysts and accelerators, with their proportions.
